According to the AutoZone | Auto Parts & Accessories | Repair Guides & More schematic, that car has (3) separate temperature sensors.The above has been verified with a separate shop manual (Haynes).

1 is for an idiot light. It is a switching type. A dark green wire is connected to it.

next is for the gauge. It is the resistor type. It also has a dark green wire connected to it.

And the third sensor is for the ECM. It has black and yellow wires connected to it.

The sensor for the idiot light can be tested by grounding it to see if the light lights.
The sensors could be mixed up.
